Application filed January 2%, 1966. Serial Ila, 2981488.

To aIZZ whom it may concern: Secured in any suitable manner to the 55 Be it known that 1, Reno ROBIN BELL, a valve-casing is a supporting-frame consisting citizen of the United States residing near of a pair of spaced uprights 8, connected by Qhickasha, in the county of Gaddo, Oklacross-bars 9, and through which is slidably 5 home Territory, have invented a new and mounted for vertical movement the valve- Patented July 24, 1906.

useful Automatic FluidPrc ssure Regulator, of which the following is a specification.

This invention relates to automatic fluidpressure regulators for gas stoves, burners,

and the like, and has for 1ts object to provide improved means for effecting the automatic closing of the intake-valve should the res-' surein the supply-pipe be materially re need or for any reason temporarily cut oil.

A flirt or object of the invention is to provide a lever for normally holding the valve in olppn position, said lever being connected, t ough the medium of a pivoted trigger, to a trip device movable to release the lever when the duced. I

A still further oh'ect is to generally improve this class of evices, so as to add to their utility and durability, as Well as to reduce the cost of manufacture.

With these and other objects in view the invention consists in the construction and novel combination of partshereinafter fully described, illustrated m the accompanying drawings, and pointed out in the claims hereto appended, it being understood that varione c an es in form, proportions, and minor details 0 construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

In the accompanying drawings, forming a part of this specification, Figure 115 a side elevation of a gas-re ator constructed in accordance with my invention. Fig. 2 iso top plan view of the pivoted trigger and trip device. Fig. 3 is a vertical sectional view taken on the line 3 3 of liig. 1.

Similar numerals of reference indicate corifisponding parts in all the figures of the The improved regulator principally designed for use in connection with gas-stovesand it consists of a section of pipe 5, oneon of which is provided with an intake-valve 6 for connection with the main supply-pipe 7 while the op osite end thereof is threads for the recept on of a pipe leading to the gasbumers. l

pressure in the supply-pipc is re- Eights 8 and having its adjacent or short end urcated for the rece tion of the valve stem. The opposite or ong end of the lever 13 is Cprovide with a laterally-extending lug 15, a opted to engage thedivergent arms 16 and 17 of a ivoted lock-trigger 18. The tri ger 18 is pivoted at 19 to a post or standar 20, extending vertically from the flat surface 21 of the zips-section 5, the lo arm 16 of the trigger eing normally held in orizontal position, so as to prevent pivotal movement of the lever 13, by a spring-catch 22, carried by a trip device 23. The trip device 23 is pivoted at 24 between a pair of s aced lugs 25, secured to or formed integr with the fiat surface of the pipe 5, and extending laterally from one side of the is a weighted arm or projection 26, adapted to engage a sto -lug 27 for the tilting movement of t e trip and supportingthe latter in vertical position,

Threaded in the pipe-section 5 in advance of the trip device is an auxiliary pipe 28, to

the free end of which is secured a cup 29,- adapted to contain a cl uantity of mercury 38, and mounted for siding movement on said tube is a closed tube or cylinder 31, having one or more weights 31 resti on the bottom thereof, as shown. Extendm laterally from the trip are arms 32, whic the tube 28 and extend in the ath of movement of the cylinder 31, so is at when the pressure in the ipc 5 is reduced the weights will cause the cy inder to engage the arms and tilt the trip, thereby relieving the trigger and valve-lever and causing the spring to automatically close the valve.

The spring-catch 22 is preferabl provided with an inclined or beveled head 3, so as to span permit the long arm of the pivoted trigger to e readil T locked in engagement with the trip device, t e lateral movement of the catch being limited by a yoke 34.

Under ordinary conditions the gas will flow from the main supply-pi e 7, through the pipe 5, to the burners wit out affecting the valve. Should, however, the pressure in the supply-pipe be materially reduced or for any reason the sup ly of gas to the burners temporarily cut ofl the cylinder will depress the arms 32 and tilt the trip to release position, thereby releasing the trigger and permitting the spring to close the valve, as before stated. It will thus be seen that the cylinder acts as a governor to automatically regulate the supply of gas to the burner. To reset the device, it is merely neeessar r to move the trip until the arm 26 engages the stop-lu 27, and subsequently force the long arm 16 o the trigger past the inclined head of the spring-catc when the valve will be locked in open position.

Having thus described the invention, what is claimed is 1. In an automatic pressureregulator, a su ly-pi e, a valve, a lever for normally holding t 1e valve in open osition, a trigger provided with angularly-disposed arms for engagement with the lever, a trip ada ted to engage one of said arms for locking t 1e trigger in set position, and means for actuating the trip to release the trigger and close the valve when the pressure in the supply-pipe is reduced.

2. In an automatic pressure-regulator, a supply-pipe, a valve, an auxiliary pipe communicating with the supplypipe, a lever for normally holding the valve in open position, a trigger provided with angularly-disposed arms adapted to engage the lever, a trip adapted to engage one of said arms for lockin the trigger in set osition, and a closed tube slidably mounte on the auxiliary pipe for actuating the trip to release trigger and close the valve when the pressure in the supply-pilpe is reduced.

3. 11 an automatic pressure-regulator, a supply-pipe, a valve, an auxiliary pipe communicating with the supply-pipe, a lever for normally holding the valve in open position, a standard secured to the su ply-pipe, a trigger pivotally mounted on t e standard and provided with angularly-disposed arms adapted to engage the adjacent end of the lever, a

trip provided with a spring-catch adapted to engage one arm of the trigger for locking the same in set position, and a closed tube slidably mounted on the auxiliary pipe for actuating the tri to release the trigger and close the valve wlien the pressure in the supplypipe is reduced.

4;. In an automatic pressure-regulator, a supply-pipe, a valve, a frame carried by the va ve-casmg, a lever pivoted to the frame and having its short end engaging the valvestem, a spring interposed between the lever and frame, a pivoted trigger adapted to engage the long end of the lever, a trip for locking the trigger in set position, and means for actuating the tri to release the trigger and close the valve w ion the pressure in the supplypiIpc is reduced.

5. n an automatic pressure-regulator, a supplypipe, a valve-casing, a valve, a frame secured to the valve-casing, a lever ivoted to the frame and having its short en engag; ing the valvestem, a spring interposed between the lever and frame, astandard secured to the supplypipe, a trigger pivoted to the standard and adapted to engage the long end of the lever, a pivoted trip for locking the trigger in set position, means for limiting the pivotal movement of the trip, and means for actuating the tri to release the trigger and close the valve w ien the pressure in the sup-- ply-pi e is reduced.

6. n an automatic pressure-regulator, a supply-pipe, a valve-casing, a valve, a frame carried by the valveoasing, a lever ivoted to the frame and having its short en engaging the valve-stem and its long end provided with a laterallyextending lug, a spring interposed between the lever and frame, a standard secured to the su ply-pipe, a trigger pivoted to the standard and provided with divergent arms embracing the lug on the lever, a pivoted trip adapted to engage one of the trigger-arms for locking the trigger in set position, and means for actuating the tri to release the trigger and close the valve w on the pressure in the su ply-pipe is reduced.

In testimony t at I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.
